Category: ATM, Vendor: Nortel

Description: Provides Token Ring (IEEE 802.5) interface extensions for Nortel Centillion switch module management.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is CENTILLION-DOT5-EXTENSIONS-MIB?

CENTILLION-DOT5-EXTENSIONS-MIB is a Bay Networks (Centillion Token Ring switch heritage, later Nortel) proprietary MIB extending Token Ring (802.5) interface parameters. Its extension table, keyed by ifIndex, records port-connection type, speed-sense setting, and admin ring speed, while a companion S5-Token-Ring extension table records front-port-connect and operational-backplane-attachment status. As a configuration/status MIB it lets an administrator confirm ring speed and port-connection settings on a Centillion Token Ring switch. It is deployed on Bay Networks (Nortel) Centillion Token Ring switches. Engineers can download the CENTILLION-DOT5-EXTENSIONS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CENTILLION-DOT5-EXTENSIONS-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Bay Networks (Nortel) Centillion Token Ring switches

Monitoring Examples

An administrator checks cnDot5ExtnAdminRingSpeed to confirm the configured Token Ring speed on a Bay Networks (Nortel) Centillion switch port.

What Can Be Monitored

Token Ring port connection/speed configuration

OBJECT-TYPE

OIDs

OID symbolic	OID numeric	Type	Access	Description
cnDot5Extensions	1.3.6.1.4.1.930.3.3
cnDot5ExtnTable	1.3.6.1.4.1.930.3.3.1		not-accessible	This table contains Token Ring interface parameters and state variables, one entry per 802.5 interface.
cnDot5ExtnEntry	1.3.6.1.4.1.930.3.3.1.1		not-accessible	A list of Token Ring status and parameter values for an 802.5 interface.
INT cnDot5ExtnIfIndex	1.3.6.1.4.1.930.3.3.1.1.1	INTEGER	read-only	The value of this object identifies the 802.5 interface for which this entry contains management information. The value of this object for a particular interface has the same value as the ifIndex object, defined in [4,6], for the same interface.
TRP cnDot5ExtnPortConnType	1.3.6.1.4.1.930.3.3.1.1.2	TrPortConnType	read-write	The type of connection used on this port. Setting a value to this object requires the port to be reset and re-opened before taking effect. Allowable connections for TR4 are: Station - (default for TR4) the port is configured as a standard ring station, Ring-In/Ring-Out - the port is connected to the Ring-In or Ring-Out port of a MAU with an appropriate cable. DTR - the port has a direct connection to a ring station. A different set of connection type for TR8 are : Hub, Station, Bay/SNPX RO, Bay/SNPX RI, Other RO, Other RI, FDTR Hub, FDTR Station
ENA cnDot5ExtnPortSpeedSense	1.3.6.1.4.1.930.3.3.1.1.3	EnableIndicator	read-write	Indicates whether speed sensing is enabled (default), or disabled on the port. This is used in conjuection with the RingSpeed to either match or force to the configured speed.
INT cnDot5ExtnAdminRingSpeed	1.3.6.1.4.1.930.3.3.1.1.4	INTEGER	read-write	The configured ring speed of the port. The speed will take effect on the next opening of the ring. The speeds of 'force' indicates that the port should enter the ring regardless of the current ring speed. The 'match' speeds indcate the the port should insert at the configured speed, only if the current ring speed matches the port speed. The operational ring speed may be obtained by the usual dot5RingSpeed object. The 'auto detect' indicates that the ring detect and insert at the current ring speed.
cnS5TrExtnTable	1.3.6.1.4.1.930.3.3.2		not-accessible	This table contains additional Token Ring interface parameters and state variables, one entry per 802.5 interface for 5000BH token ring cards.
cnS5TrExtnEntry	1.3.6.1.4.1.930.3.3.2.1		not-accessible	A list of Token Ring additional status and parameter values for an 802.5 interface for 5000BH token ring cards.
INT cnS5TrExtnIfIndex	1.3.6.1.4.1.930.3.3.2.1.1	INTEGER	read-only	The value of this object identifies the 802.5 interface for which this entry contains management information. The value of this object for a particular interface has the same value as the ifIndex object, defined in [4,6], for the same interface.
INT cnS5TrExtnFrontPortConnect	1.3.6.1.4.1.930.3.3.2.1.2	INTEGER	read-write	If enabled, front port insertion is allowed. This setting has no meaning other than in tr8PortHub mode.
INT cnS5TrExtnOperBkplaneAtt	1.3.6.1.4.1.930.3.3.2.1.3	INTEGER	read-only	This object returns the operating backplane attachment state of a token ring port. For the ports that do not have backplane attachment capability, notCapable(2) is returned.
